How to store car without rodent infestation?

I use to do the moth ball trick too when I kept me car in my dads pole barn. The only thing was that my eyes watered so bad from the odor trying to drive the car in the spring that I couldn't hardly stand it. The smell never really left totally either. So I started keeping lot's of decon and mouse traps all around the car and caught them that way and that kept them out of the car. Be SURE to lower your sun visors down too because they will use them as a support in the headliner to lay against while they CHEW through your headliner. Speaking from experience!!
